If the air conditioning unit isn’t cooling, you must call a professional air conditioner repair service. But before that, you can try some easy troubleshooting to fix this problem. Here are a few quick troubleshooting tips when the AC unit isn’t cooling.
5 Easy
Troubleshooting Guide: Air Conditioner Isn’t Cooling
1. Check the
Power
Before jumping into other troubleshooting guides,
check whether your AC unit is connected correctly to the power source or not. Besides,
check the condition of the AC power chord as well.
If the power chords are damaged, replace them ASAP.
While replacing the power chords, follow all the safety protocols and unless
you’re an expert in handling electrical components, call an electrician.
After replacing the power chords, try restarting the
AC unit. If it’s still not blowing cold air, there can be a problem with the
electrical panel. If you find out that the circuit breaker is tripped due to
heavy voltages, replace the circuit breaker and restart the cooling unit.
2. Bad
Thermostat
If the power source has no problem, check the air
conditioner thermostat. As an air conditioner thermostat is considered an AC
unit's brain, your AC unit won’t get the signals properly when it’s broken. As
a result, it won’t produce any cool air.
Turn down the AC thermostat dial button and set it to
the lowest settings. If the AC is still not blowing cool air, your AC has a bad
thermostat, and you need a thermostat replacement.
3. Check the Air
Filter
As we all know, an air filter's main function is to
block all sorts of particles and dust from entering the space, which is why it
gets clogged quickly. If you haven’t changed the air filter in the last three
months, chances are your AC unit has a clogged air filter.
Some cooling units turn off the system when it has a
clogged air filter. This feature prevents the AC unit from overheating and
other damages.
If your air conditioner has such a feature, check
the air filter. As soon as you find out that the air filter is clogged, replace
it.
4. Clean the
Compressor Unit
As the compressor unit stays outside, unfortunately,
most homeowners tend to forget about this unit. But you should know that the
compressor unit plays a major role in keeping your home cool.
When the compressor or the outdoor unit is dirty,
airflow will be stopped, and as a result, the AC unit will stop working. That’s
why before calling a professional air conditioner repair service, check the
compressor unit and if it’s clogged, clean it thoroughly.
If you don’t have enough time to clean the
compressor unit by yourself, you can do a regular AC maintenance checkup. Green
Leaf Air provides the best maintenance for air conditioner (Dallas, TX), and all their
technicians are certified and highly experienced.
5. Check the
Refrigerant Level
There is a common myth among air conditioner users
that refrigerant or coolant doesn’t deplete. Once you fill the coolant in the
air conditioner, it’ll last forever. But it’s completely a false conception
about coolant.
Like compressor or outdoor unit, refrigerant plays a
major part in cooling your space. Refrigerant or coolant absorbs the heat from
your home and releases it to the outside unit. Thus, our home becomes cool.
When you have a leak in the air conditioner,
refrigerant starts to leak from the AC unit and reduces the cooling capacity of
the unit.
If you find out that your AC unit has a refrigerant
leak, you’ll have to call nearby professional air conditioner repair service as
soon as possible. As there are some toxic chemicals in the coolant, you should
never try DIY fixes to solve this problem.

Conclusion
If you have an old AC unit, which is over ten years
old, you should replace it. Because after 10 to 12 years, the AC unit starts to
perform poorly and requires frequent repairs. Besides, if you think from the
financial POV, it’s not viable to repair an old unit again and again.
